Arterial blood-flow is simulated using the shear-rate dependent
Carreau-Yasuda fluid model through idealized bifurcating arterial
geometries. Given that the whole cardiovascular system would
be too large and complex to model, a resistance boundary condition
is used to incorporate the downstream domains in a truncated
geometry. The pressure and flow-rate of a truncated geometry
with resistance outlet boundary conditions are compared to the
pressure and flow-rate at the same region of a non-truncated geometry
with traction-free outlet boundary conditions.
